I can't figure out how to complete the task. Has anyone programmed in machine codes for the K1810VM86 microprocessor?

Question

Programming

This type of task:

5. A four-byte code is given, located at address 00500h. Count the number of strings 1-0 (including interbytes) and write to address 00600h.

The difficulty is that the addresses where what should be stored are clearly given here, and I don’t understand how segment offsets work here.
